Share this Post:

This Commissioning Code (CC) released by the Chartered Institution of Building Services Engineers (CIBSE), provides an overview of the management arrangements required to ensure that building services systems are commissioned to meet the objectives of Part L of UK’s Building Regulations. It is intended for commissioning managers and engineers, services installers, designers and facilities managers. CIBSE Commissioning Code M, produced in collaboration with the Commissioning Specialists Association presents current standards of good commissioning practice in the form of recommendations and guidance. The Code acknowledges that it may be used in a variety of contractual frameworks, and seeks to enable services engineers to improve the performance of buildings through better commissioning
